Protection
Over voltage, under voltage, over temp, over current, open winding, communication cable disconnection
Idle Current Reduction
Reduction range of 0 - 90% of running current after a delay selectable in milliseconds
Controller
Anti-Resonance
Raises the system-damping ratio to eliminate midrange instability and allow stable operation
throughout the speed range of the motor
Torque Ripple
Smoothing
Allows for
fi
ne adjustment of phase current waveform harmonic content to reduce low-speed
torque ripple in the range of 0.25 to 1.5 rps
Auto Test & Auto
Setup
Auto test and setup at power on (ie. motor resistance, and capacitance) to optimize your system
performance.
Non-Volatile Storage
Con
